Reading the model number
ML is Lennox's Merit line, and 14 is the nominal SEER2 class for the ML14KP1 series. K is R-454B, P is a heat pump outdoor unit, 1 is the single-stage compressor, 030 is 2.5 tons, and 230 is 208/230V single-phase. The characters after 230 on the unit label are Lennox revision codes. The AHRI Directory lists it as ML14KP1-030-230A**.
What it pairs with
The AHRI Directory lists it with Lennox CBK45UHET, CBK45UHPT, CBK45UHVT, and CBK47UHET air handlers, and with CK40CT, CK40DT, CK40HT, and CK40UT coils on Lennox gas furnaces for dual fuel. The best match we carry is a CK40CT-36B-71 coil on an ML180UH090XE48B furnace, at 16 SEER2 and 7.8 HSPF2. For heating, the CBK47UHET-036-230-71 air handler reaches 8.2 HSPF2.
R-454B systems need a refrigerant detection sensor at the indoor unit, so confirm your coil or air handler has one.
Sizing and fit
With a gas furnace, you need a dual-fuel thermostat or a zoning system with dual-fuel control. Size it from a Manual J load calculation, checking heat output at your local winter design temperature.
It cools down to 45°F outdoor air without extra controls, or 30°F with Lennox's optional low ambient kit.
